[Oxyd][0.17.72] Pathfinder Crash (abstractNodeIt != search.abstractNodes.end() was not true)

[Veden]

Uses just the Rampant mod.

Destroy the nest with a nuke either directly north or east of you, game should freeze and produce stack trace.

Issue is that you are using "path_resolution_modifier = -8". This means that abstract nodes cover 1 chunk each (32x32), but base node covers 64 chunks (256x256). At some point goal position is badly aligned because of resolution, chunk that contains badly aligned goal position does not contain any abstract nodes and there is crash. Fix will be to limit path_resolution_modifier to be not less than -5

Thanks, should be fixed in 0.17.73. There will be no additional limit on path_resolution_modifier.
